SPECIFICATION forming part of Letters Patent No. 722,038, dated March 3, 1903.

Application filed October 7, 1902.

To (all whom, it mfr/y 0071/067172.:

Beit known that I, FRANCIS P. PIDGEON, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, have invented new and useful Improvements in Envelope, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and useful improvements in envelops, whereby a number of envelops arranged in a continuous length are detachably connected with each other to allow of running the envelops through a type-writing machine for addressing the envelops in a convenient and quick manner.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter, and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a rear elevation of the improvement. Fig. 2 is a transverse section of the same, and Fig. 3 is a face view of part 0f the blank for forming the envelops.

The envelops A, A', A2, and A3 are made from a single blank of paper and arranged in a continuous length, as plainly indicated in Figs. 1 and 2, and each of the said envelops consists of a front B, side flaps C, a top or closing flap D, and a bottom flap E, of which the side aps C and the bottom flap E are fastened together in the usual manner, and the upper edge of the top ilap D is integrally connected with the upper edge of the bottom flap E of an adjacent envelop. The junction between the top flap D and the bottom iiap E is scored or perforated, so as to allow of conveniently det-aching the top flap of one envelop from the bottom iiap of the adjacent envelop to separate an envelop from the continuous length of envelops.

In making the series of envelops described a single piece of paper is formed into a blank, (shown in Fig. 3,) and the side iaps of each Serial No. 126,313. (No model.)

envelop-blank are folded over, together with the corresponding bottom flap E, and fastened together in the usual manner, while the top flap of one envelop is loosely folded onto the bottom flap E of the adjacent envelop, so that the series of envelops form a continuous front face composed of the fronts B of the several envelops. Now this continuous length of envelops can be readily run through a typewriting machine to address the envelops successively ina convenient and quick manner. The envelops addressed are readily detached one from the other along the score-line or perforation extending at the joint between the top iap of one envelop and the bottom flap of an adjacent envelop.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A series of envelops made from a single blank and arranged in continuous length, each envelop comprising a front, side flaps adapted to be folded inward toward each other, a top or folding flap, and a bottom flap adapted to be folded inward and secured to the side flaps, the closing flap of one envelop having its free end integrally connected with the upper edge of the bottom flap of an adjacent envelop and sealed to its side flaps, the construction being such that the blank may be formed into a series of envelops without tearing or detaching an)7 portion of such blank.

2. A blank for forming a series of envelops in continuous length, comprising a plurality of fronts, side Iiaps on each front and top and bottom flaps on each front, the top and bottom ilaps being integrally connected and so formed that a series of connected envelops may be made from the blank without separating or tearing a portion of said blank.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANCIS P. PIDGEON.
